For fixing this regression bug 39354 if you use the test script from 39373 for now (before 39373 is fixed) you should only look at the 3G size .iso file results (less than 4G size where bug 39373 kicks in).

That means same should be in RHEL 6.4 and CentOS 6.4. They come with 0.81 and it works. Then I built 0.90 from sources and installed it and the defect showed. Then I built 0.81 from sources this time, no defect again. Reproducibly 0.90 is broken versus 0.81 works.

So if you have a RHEL 6.x or derivative, grab the .iso I've linked and see defect with 2/3rd of 3000+ files e.g.
